Here’s some information on the game right from the developers:

You are a daring pizza delivery boy and your restaurant’s guarantee does not have an exception for alien invasions. Make your way through an 8-bit land filled with platforms, pitfalls, crazy power ups, dangerous obstacles, and of course, aliens! Grab pizza slices along the way, and deliver them to houses for big bonuses. World 1-1 combines the style and fun of retro arcade games from the 1980s with the fast paced action of modern endless runners.
